Check Cass’s post on this, checklist entries are here: On the right triangle, tan is leg1/leg2 , on the unit circle tan is sin/cos tan is sin /cos =P Tan on unit circle: the tan of any angle is always … Continue reading →

Trig equations 1 (no b or h involved): you can see some directly from blogs, like Cass’s post  and Tanyse’s post and here are those that came in via the checklists: Firstly, we must make equation equal to zero since we … Continue reading →
